Radiation-induced cancer in the population of villages around MAPE Mydlovary
KREJČÍ, Klára
In 1959, the building of chemical preparation plant of uranium ore MAPE Mydlovary was initiated in a small village Mydlovary, near České Budějovice. In October 1962, the operation and processing of the uranium ore started. During operation, about 17 million tons of uranium ore were processed and the material from processed uranium ores was stored into the contiguous sludge lagoons. The operation of this plant was terminated in November 1991. The premises of MAPE Mydlovary were partially liquidated, decontaminated and handed over for privatization, nowadays there are recovery and reclamation works in process. Even though, MAPE Mydlovary is nowadays one of the most dangerous strains for environment, which emerged after mining and processing of uranium ores in the Czech Republic. The projection is to liquidate the consequences of this process for many more years from now. In immediate closeness to the premises of MAPE Mydlovary there lie the villages Mydlovary, Olešník and Zahájí. It can be assumed that during the processing of uranium ores and subsequent storing of waste into the contiguous sludge lagoons there could have been some impact on the inhabitants of these villages by radio nuclides. The possibility that there are still some sources of contamination and effect on the inhabitants of the three neighboring villages cannot be excluded nowadays, even after almost 23 years after the shutdown of the plant. For this reason this diploma thesis is dealing with the effects of the preparation plant MAPE Mydlovary on the inhabitants of Mydlovary, Olešník and Zahájí, specifically on the amount of deaths due to cancer diseases of inhabitants of these villages. Data was collected from October 2013 till April 2014 and it includes figures from the period 1971-2010. It was collected using non-standardized interviews and was provided by practicing physicians of the investigated villages; furthermore, data was collected from websites of the Czech Statistical Office. Aim of this thesis was to analyze and compare the deaths due to cancer diseases of the inhabitants in the surroundings of MAPE Mydlovary and of inhabitants in the whole Czech Republic (whole republic´s cancer disease mortality) and evaluate the possible influence of the radiation load on the number of deaths due to cancer diseases of inhabitants in the surroundings of MAPE Mydlovary. The analysis and comparison of the number of deaths was carried out using statistical research. Non parametric testing was used for the statistical research and the so called Fisher exact test was used, which is carried out by means of statistical software www.ncss.com. For this test the level of significance - = 0, 2 was used. The influence of the radiation load on the number of deaths due to cancer diseases is statistically significant only in the village Mydlovary, where it is possible to prove statistically an increased number of deaths due to cancer diseases in comparison to the number of deaths due to cancer diseases in the whole Czech Republic. Based on the evaluation of the obtained data we can state that the chemical preparation plant of uranium ore MAPE Mydlovary most likely had and still may have a negative impact on the inhabitants of the neighboring villages, especially on the inhabitants of the village Mydlovary. For this reason it is very important to continue with the recovery and reclamation works in the premises of the chemical preparation plant of uranium ore MAPE Mydlovary and their main objective is to protect the inhabitants of surrounding villages against possible exposure to the radio nuclides. Nevertheless, the impacts of processing the former chemical preparation plant of uranium ore MAPE Mydlovary will be eliminated for many more years.

Sorption and Stabilization of Metals/Mettalloids by Innovative Synthesized Sorbent Amochar.
Ouředníček, P. ; Trakal, L. ; Komárek, M. ; Pohořelý, Michael
Remediation of contaminated soil which is based on stabilization and immobilization of potential\nhazardous substance by sorption materials has been studied intensively nowadays. Biochar – activated organic carbon belongs to this group of stabilizing agents which can adsorb wide range of contaminants, including metals/metalloids. Surface area of the biochars is quite large in general and functional groups (e.g. COO–) can form chelates or alkaline elements on the surface, which is represented by cation exchange capacity. Altogether with the high pH values (7.00 – 10.00), biochars are quite effective sorbents and can adsorb metals/metalloids from the solution (ground water), especially in acidic soils (in the environments affected by intensive mining activities). Sorption\neffectiveness can be increased (especially for As (V) or Cr (VI) sorption) by modification of biochar by various types of secondary oxides. Innovative sorbent AMOchar (AMO + biochar) has been synthesized currently. The product was prepared by adding of biochar to the reaction solution during amorphous manganese oxide (AMO) synthesis. The AMOchar was formed mainly by Mn-oxalates which had coated surface of the pristine biochar. AMOchar composite was able to remove significantly higher amounts of various metal(loid)s from the solution despite the rather high pH of the material. Sorption effectiveness was high not only in case of Pb (II) sorption (almost 99%), and Cd(II) (51.2%), but also a very high amount of As(V), 91.4%. Additionally, both AMOchar composite was able to reduce Mn leaching. This can avoid potential post-contamination caused by the dissolution of less stable Mn-oxalates as observed in the pure AMO.

Improving labour productivity: How to determine standard time for performing specific tasks in the selected organization
BARTOŠKOVÁ, Martina
This bachelor thesis focuses on the standard time needed for specific tasks in the selected organization, as well as on the appropriate methods for its determination. The findings serve as a basis for the formulation of measures which should be taken to improve labour productivity. The methods include the standardization of tasks, time study and computer-based data analysis (Microsoft Excel spreadsheets). The theoretical part of the paper discusses the nature of job production, the methods appropriate for the calculation of standard production time and the ways to ensure efficient work and time management in the given factory. Apart from these, a complete description (history, facility layout, pre-production and production stages, machines and materials) of the selected organization is provided to serve as a background for the case study presented in the practical part. This includes the list of production tasks, production time tables and time standards along with materials necessary to facilitate production. The aim of the thesis is to help the organization improve its labour productivity and provide it with the algorithm which can be used to determine production time for similar orders.
